"Precision is enormously important to our customers – and we have to verify it with our measuring systems," says Axel Küpper, Senior Manager, Global Sales and Application, Gear Milling Solutions at Sandvik Coromant, the world leader in tools and tool solutions. "If the profile of a gear wheel for a crane is not manufactured precisely, the manufacturer may have just wasted 40,000 euros." This was precisely the reason why the subject of metrology was so important for Sandvik when the company decided to enter the market for gear hobs.
Sandvik was already using ZEISS coordinate measuring machines. What was missing, however, was a specialized measuring program that met three criteria: first, during the measurement, all 17 DIN 3968 requirements on a hob of a certain quality class must be covered. Second, the results of this measurement should be automatically entered in the measurement report. Finally, the software should facilitate fast measurements. Sandvik was unable to find software on the market that met their needs. Their inquiry to ZEISS led to a development collaboration.
